Just installed Duplicati today and running my first backups.
This a stand-alone machine backing up to a 5TB USB3 Seagate drive.
Windows 10 Pro (22H2)
HP-Z440 64GB RAM
The first backup set went well and completed in a reasonable amount of time. 20.82GB in 00:15:04
My second set is going much slower, it is significantly larger 1.32TB, 73,172 files, in 1,969 folders. What is troubling is that the throughput is degrading consistently through the process. It was transferring 50MB/s at first and with 57,000 files remaining it is down to 19.45 MB/s and has been running for 7 hours. With only 22% of the files completed and down to less than half of the throughput, I’m wondering if this will complete. I’ll leave it running overnight and hopefully it will.
- No encryption
- Volume Size: 100MB
Thanks in advance!
::next day…
18 hours into the backup. Throughput seems to have settled at 17 MB/s. 15K files remain.
Will a different Volume Size affect this?
Is there a way to commit more RAM to the process? And would that help.
I see some conversation about Block Size, should that be adjusted? File sizes are mostly around 25MB each.
I wanted to run these to my NAS as a parallel backup. But that looks like it could take days to get started and the ability to restore from there seems dubious.
